Description
Technical field
The present invention relates to crop planting fields, and in particular to a method of screen drought-enduring soybean varieties.
Background technique
Soybean is Poales, grass family, soybean plants, annual sturdy draft, fibrous root yellow-white, spongioplasm, diameter
About 3 millimeters.The flowering fruit bearing stage 6-12 month.Mainly originate in the province such as Hubei China Qichun, Hunan, Hebei, Jiangsu, Fujian.Soybean kernel is
It is edible for people can be made into congee, meal, various wheaten food for one of food resource of Chinese tradition.It is especially more suitable to the old and the weak patient.
It is sweet in flavor, light, cold nature.Mountain village is wherein flowed as the most famous of source area using Qichun four, there is invigorating spleen to remove dampness, clearing away heat and eliminating pus, beauty
Beautifying function.
For soybean, the development degree of underground root system determines the power of drought-resistant ability.Intend according to underground root system
Development degree identifies the drought resistance of soybean different cultivars of the same race, but the development degree of root system is affected by matrix.Cultivation
Discrete phase is more suitable for the growth of soybean root system for soil, for example cultivation matrix total porosity is bigger than soil matrix.In order to
The growing environment built to root system, it is necessary first to develop the cultivation matrix of a suitable soybean.
Summary of the invention
An object of the present invention is to provide a kind of methods for screening drought-enduring soybean varieties.
A kind of method for screening drought-enduring soybean varieties of the invention, includes the following steps: S101: by corn stover, bone
